FAIRFAX, Va. (AP) — A deputy who fatally shot a hospital patient wielding a metal sign post was also involved in the death of an inmate last year shot multiple times with a stun gun.

Police on Thursday identified Patrick McPartlin, an 18-year veteran of the Fairfax County Sheriff's Office, as the deputy who shot and killed Jovany Martinez outside Inova Fairfax Hospital last month.

McPartlin, who is Asian-American, is on administrative leave while the shooting is investigated. Police say Martinez was having a mental episode and had injured one person when he charged McPartlin with the post.

McPartlin was also part of a team that restrained Natasha McKenna last year as she was removed from a jail cell. McKenna, who also suffered from mental illness, died after receiving four Taser shots during a 15-miunte struggle.
